Question: [QUESTION]Which country is highlighted?
Solution: This country is Vanuatu.
Does Vanuatu have any territorial disputes?
Vanuatu claims to own Matthew and Hunter Islands, which are disputed islands. In other words, multiple countries or groups claim that the islands rightfully belong to them.
France has controlled the islands since 1929. But shortly after gaining independence in 1980, Vanuatu claimed to rightfully own the islands. It points to underwater geographic features and legends passed down by its people to argue that it has stronger connections to the islands than France. No one lives on the islands today.

Question: [QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Solution: The magnets in Pair 1 attract. The magnets in Pair 2 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force.
Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.

Question: [QUESTION]Based on this information, what is Muffin's phenotype for the ear type trait?
Solution: You need to determine Muffin's phenotype for the ear type trait. First, consider the alleles in Muffin's genotype for the ear type gene. Then, decide whether these alleles are dominant or recessive.
The allele for normal ears (E) is dominant over the allele for dumbo ears (e). This means E is a dominant allele, and e is a recessive allele.
Muffin's genotype of Ee has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Muffin's phenotype for the ear type trait must be normal ears.

Question: [QUESTION]Which animal's feet are also adapted to walk on snow and ice?
Solution: Look at the picture of the polar bear.
The polar bear has furry feet with large pads. Its feet are adapted to walk on snow and ice. The fur can help keep the polar bear's feet warm. The large pads help spread its weight over a larger area. This allows it to walk on ice without slipping and to walk on snow without sinking in too deep.
Now look at each animal. Figure out which animal has a similar adaptation.
The Eurasian lynx has furry feet with large pads. Its feet are adapted to walk on snow and ice.
The tokay gecko has wide, sticky toes. Its feet are not adapted to walk on snow and ice. The tokay gecko uses its feet to climb trees and walk on leaves.

Question: [QUESTION]Which logical fallacy is used in the text?
Last year, the city of Lanberry allocated more money to public parks. This year, however, littering increased, so the increase in park funding must have been responsible.
Solution: The text argues that increased park funding was responsible for an increase in littering. However, even though littering increased after funding to parks was increased, that doesn't necessarily mean that the funding was responsible. This illustrates a type of logical fallacy known as false causation.

Question: [QUESTION]Which country is highlighted?
Solution: This country is Papua New Guinea.
Why does Papua New Guinea share its island with another country?
Papua New Guinea takes up the eastern half of the island of New Guinea. The western half is part of Indonesia, an Asian country.
Beginning in the 17 th century, several countries took control of different parts of the island of New Guinea. By 1922, Australia controlled the entire eastern half of the island, and the Netherlands controlled the western half. In 1963, control over the western half was transferred to Indonesia, which had just gained independence from the Netherlands. Many people in western New Guinea did not want to become part of Indonesia, though, and some people in this area are still fighting to leave Indonesia today. The eastern part gained independence from Australia in 1975 and became Papua New Guinea.

During this chemical reaction, the solution becomes ().
Solution: To determine whether the solution becomes warmer or colder, look for the text that describes the movement of thermal energy during the reaction.Pickling is used to prevent foods such as meat and vegetables from spoiling too soon. Food that has been pickled may remain edible for more than a year! One type of pickling involves soaking the food in a solution of water and sodium chloride (NaCl). When sodium chloride is dissolved in water, sodium ions (Na+) and chloride ions (Cl−) form in the solution. During this process, a small amount of thermal energy is taken in from the surroundings.The underlined text tells you that thermal energy is taken in from the surroundings. Because thermal energy moves out of the surroundings and into the reaction, the temperature of the surroundings decreases.The surroundings include the solution that the reaction takes place in. So, the solution becomes colder.

Question: [QUESTION]What do these two changes have in common?
a piece of apple turning brown
burning a candle
Solution: Step 1: Think about each change.
A piece of apple turning brown is a chemical change. The apple reacts with oxygen in the air and turns into a different type of matter.
If you scrape off the brown layer of the apple, the inside is still white. The inside hasn't touched the air. So the chemical change didn't happen to that part of the apple.
Burning a candle is a chemical change. Both the wick and the melted wax burn. They react with oxygen in the air and turn into soot, carbon dioxide, and water.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are chemical changes. They are not physical changes.
Both are chemical changes.
Both changes are chemical changes. The type of matter before and after each change is different.
Both are caused by heating.
Burning is caused by heating. But a piece of apple turning brown is not.
